Abstract
Description
Not Protected | The network element has no | ||
secondary ITM-SC assigned to | |||
protect it, i.e., the network | |||
element is not participating | |||
in the geographic redundancy | |||
scheme and is in the ITM-SC's | |||
not-protected |
|||
Protected | The network element is | ||
currently protected by a | |||
secondary ITM-SC. The | |||
network element is in the | |||
primary ITM-SC's protected | |||
|
|||
Protected Disabled | The protection of the network | ||
element is currently | |||
disabled, but the network | |||
element is part of the | |||
protected |
|||
primary ITM-SC. (A user may | |||
manually switch a network | |||
element from protected to | |||
protected disabled). | |||
Protecting | The network element is being | ||
protected by the secondary | |||
ITM-SC and, therefore is in | |||
the secondary ITM-SC's | |||
protecting |
|||
attribute does not indicate | |||
whether the secondary ITM-SC | |||
is actually managing the | |||
network element. | |||
Protecting Disabled | The protection afforded by | ||
the secondary ITM-SC is | |||
currently disabled. | |||
Actively Managing | The primary ITM-SC has | ||
management control of the | |||
network element. This | |||
attribute value is entered by | |||
the primary ITM-SC when the | |||
primary ITM-SC first enters | |||
the geographic redundancy | |||
scheme or resumes control of | |||
a network element. This | |||
state is irrelevant to the | |||
association state of the ITM- | |||
SC to the network element. | |||
No Control | The ITM-SC does not have | ||
control of the network | |||
element nor is it expected to | |||
be trying to gain control. | |||
Actively Managing | The secondary ITM-SC | ||
currently has management | |||
control of the network | |||
element. The attribute value | |||
is changed to actively | |||
managing by the secondary | |||
ITM-SC when it gains its | |||
first association after a | |||
switch | |||
Expecting Management | The secondary ITM-SC is | ||
currently trying to gain | |||
management control (i.e., to | |||
enter the actively managing | |||
state) by issuing association | |||
requests to the network | |||
element. | |||
No Control | The secondary ITM-SC does not | ||
have nor is it trying to gain | |||
control of the network | |||
element. | |||
Manual | The primary ITM- |
||
instigated the protection | |||
switch for a network element | |||
and the secondary ITM-SC is | |||
expected to have management | |||
control, i.e., have a | |||
management control status of | |||
Actively Managing and the | |||
primary ITM-SC is expected to | |||
have a management control | |||
status of No Control. | |||
Automatic | The secondary or primary ITM- | ||
SC automatically instigated | |||
the protection switch for a | |||
network element. The | |||
secondary ITM-SC is expected | |||
to have management control, | |||
i.e., have a management | |||
control status of Actively | |||
Managing and the primary ITM- | |||
SC is expected to have a | |||
management control status of | |||
No Control. | |||
No Switch | Normal operation. The | ||
primary ITM-SC has a | |||
management control status of | |||
Actively Managing while the | |||
secondary ITM-SC has a | |||
management control status of | |||
No Control. | |||
